A recent study, published by Cell and Fox News, indicates that the Corona virus tends first to entrench itself in the nasal cavity, and then to exudate it in the lungs. Scientists at the United Nations Medical College believe that their study strongly supports the wearing of large-scale Tatami masks as a way to prevent infection.
Richard Boucher, associate professor of the study, and professor of medicine and director of the Marisco Lung Institute at the United Nations School of Medicine, said in a statement: "If the nose is the first dominant site through which lung infections are implanted, the widespread use of masks to protect the nasal passages, in addition Any treatment strategies that reduce the virus in the nose, such as washing the nose or anti-retroviral nasal sprays, can be helpful. "
Scientists used different isolators to find out how efficient it can affect cultured cells from many parts of the human airway for one of the experiments.
They discovered a pattern of continuous variation, or progression, from a relatively high infection of SARS-CoV-2 in the cells lining the nasal passages, to a lower infection in the cells lining the larynx and bronchi, and then to a relatively low infection in the lung cells.
Scientists found that ACE2, the cell surface receptor that the virus uses to enter cells, was more abundant on the cells of the lining of the nose and less abundant on the surface of the cells of the lower airway. This difference can explain, at least in part, why the endometrium cells in the upper airway are more susceptible to infection.
